Open innovation: the experience of NaturTEC-Kids Living Lab in the co-design of a video game to engage children and adolescents with nature

[EN] The aim of this paper is to describe and analyze the process of co-creation and evaluation of an educational video game application called “Natur-Kingdom,” developed within the framework of the NaturTEC-Kids Living Lab with the active participation of children and adolescents. This article aims to demonstrate how the integration of end users into the creation process of this techno-educational solution enabled the identification and adaptation of key elements, focusing on technology’s role in connecting children to the natural environment, fostering ecological awareness, and promoting pro-environmental behaviors. Additionally, it aims to highlight the effectiveness of co-design, testing, and evaluation sessions, in identifying areas for improvement and optimization in the design, ensuring that the final technological system meets its pedagogical objectives and remains accessible and appealing to its target audience.
